Description
BACKGROUND OF THE INVENTION
[0001] Field of the Invention
[0002] The present invention relates to Internet of things,
wireless sensor network, smart door lock.
[0003] Description of the Related Art
[0004] The Internet of things, also known as the Internet of
objects, refers to the networked interconnection of everyday
objects It is described as a self-configuring wireless network of
sensors whose purpose would be to interconnect all things. The
concept is attributed to the former Auto-ID Center, founded in
1999, based at the time at the Massachusetts Institute of
Technology (MIT);
[0005] ZigBee is a low-cost, low-power, wireless mesh networking
standard. First, the low cost allows the technology to be widely
deployed in wireless control and monitoring applications. Second,
the low power-usage allows longer life with smaller batteries.
Third, the mesh networking provides high reliability and more
extensive range. There are three different types of ZigBee devices:
ZigBee coordinator (ZC), ZigBee Router (ZR), ZigBee End Device
(ZED): Zigbee net allows the ZED node to be asleep a significant
amount of the time thereby giving long battery life. ZigBee devices
are required to conform to the IEEE 802.15.4-2003 Low-Rate Wireless
Personal Area Network (WPAN) standard. The standard specifies the
lower protocol layers--the physical layer (PHY), and the media
access control (MAC) portion of the data link layer (DLL). This
standard specifies operation in the unlicensed 2.4 GHz (worldwide),
915 MHz (Americas) and 868 MHz (Europe) ISM bands. In the 2.4 GHz
band there are 16 ZigBee channels, with each channel requiring 5
MHz of bandwidth. The center frequency for each channel can be
calculated as, F.sub.c=(2405+5* (ch-11)) MHz, where ch=11, 12 . . .
26; Zigbee protocols build on recent algorithmic research (Ad-hoc
On-demand Distance Vector) to automatically construct a low-speed
ad-hoc network of nodes. In most large network instances, the
network will be a cluster of clusters. It can also form a mesh or a
single cluster. The current profiles derived from the ZigBee
protocols support beacon and non-beacon enabled networks.
[0006] Internet of things gateway (Hub) is a one-stop solution for
unifying your connected gadgets and controlling them from one
simple app, instead of many. But not all hubs are created equal;
different hubs support different connectivity protocols, so it's
important to look for a hub that supports the devices you use.
Bluetooth LE, WIFI, Z-Wave, and ZigBee are all popular ways to
connect.
[0007] Bluetooth is a proprietary open wireless technology standard
for exchanging data over short distances (using short wavelength
radio transmissions) from fixed and mobile devices, creating
personal area networks (PANs) with high levels of security. Created
by telecoms vendor Ericsson in 1994; Bluetooth uses a radio
technology called frequency-hopping spread spectrum, which chops up
the data being sent and transmits chunks of it on up to 79 bands (1
MHz each) in the range 2402-2480 MHz's This range is in the
globally unlicensed Industrial, Scientific and Medical (ISM) 2.4
GHz short-range radio frequency band. Bluetooth is defined as a
layer protocol architecture consisting of core protocols, cable
replacement protocols, telephony control protocols, and adopted
protocols. Mandatory protocols for all Bluetooth stacks are: LMP,
L2CAP and SDP. Additionally, these protocols are almost universally
supported: HCI and RFCOMM; Bluetooth low energy is an alternative
to the Bluetooth standard that was introduced in Bluetooth v4.0,
and is aimed at very low power applications running off a coin
cell. It allows two types of implementation, dual-mode and
single-mode. In a dual-mode implementation, Bluetooth low energy
functionality is integrated into an existing Classic Bluetooth
controller.
[0008] Smart door locks are arguably one of the nicest of smart
home comforts. They can automatically detect your presence via the
Bluetooth connection in your smartphone (or a Bluetooth key fob)
and unlock your front door for you. They let you send electronic
keys to your friends that work only during times that you
specify.
[0009] IEEE 802.11 is a set of standards carrying out wireless
local area network (WLAN) computer communication in the 2.4, 3.6
and 5 GHz frequency bands. They are created and maintained by the
IEEE LAN/MAN Standards Committee (IEEE 802). The base current
version of the standard is IEEE 802.11-2007. IEEE802.11b and
IEEE802.11g use the 2.4 GHz ISM band, operating in the United
States under Part 15 of the US Federal Communications Commission
Rules and Regulations;
[0010] IEEE 802.15.4-2006 is a standard which specifies the
physical layer and media access control for low-rate wireless
personal area networks (LR-WPANs). It is maintained by the IEEE
802.15 working group.
[0011] Infrared emitter, or IR emitter, is a source of light energy
in the infrared spectrum. It is a light emitting diode (LED) that
is used in order to transmit infrared signals from a remote
control. In general, the more they are in quantity and the better
the emitters are, the stronger and wider the resulting signal is. A
remote with strong emitters can often be used without directly
pointing at the desired device. Infrared emitters are also partly
responsible for limits on the range of frequencies that can be
controlled. An IR emitter generates infrared light that transmits
information and commands from one device to another. Typically one
device receives the signal then passes the infrared (IR) signal
through the emitter to another device.
[0012] IR detectors (IR receiver) are little microchips with a
photocell that are tuned to listen to infrared light. They are
almost always used for remote control detection and more.
[0013] Proximity sensors detect the presence of objects without
physical contact. Since 1983 Fargo Controls' proximity sensors have
been of the highest quality, durability & repeatability to meet
today's tough industrial requirements.
[0014] Positioning Contact Switches no need intermediate actuators
by the measuring element of the switch customized for the detected
object.
